WARPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 624,541, dated May 9, 1899. Application filed January 20,1899. b'erial No- 702,841. (No model.)

To all whom it may concern:

Be it known that I, ALONZO E. RHOADES, of I-Iopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Warping-lllachines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

It is advisable in all warping-machines to stop the Winding of the yarn upon the beam.

, when there is a predetermined length of yarn thereupon, and it is the usual practice to operate the measuring mechanismfrom a small roll at the top of the warper and over which the yarns run; but there is always some slip with a device of this character, involving inaccuracy in the measuring.

My present invention has for its object the production of means for effecting the measuring without such inaccuracy and for effecting the operation of the stopping means for the warper when the predetermined length of yarn has been wound upon the beam. 2 5 I hereinafter described, and particularly pointi Various features of my invention will be ed out in the following claims.

Figure 1 is an end elevation of a warping machine of usual construction. Fig. 2, on a 1 reduced scale, is a perspective view of the main frame, the fast and loose pulleys, the, beltshipper, and the well-known means for' controlling the latter, to better enable my invention to be understood; and Fig. 3'is a per- I spective detail to be referred to. l

Referring first to Fig. 2, the end frames A f A, the fast and loose pulleys B B, the beltfork b, mounted on a sliding rod 1), the elbowlever b to efiect longitudinal movement of the rod, the rock-shaft b having a treadle or foot-board B Fig. 1, and a counterbalanceweight W, and the rocker-arm 5 fast on the rock-shaft and pivotally connected with and to operate the rod 19, may be and are all of having, as herein shown, an eccentric groove d to receive a roller or other stud cl on an arm d fast on a short rock-shaft (1 mounted in the frame A, whereby the rotation of the drum D will rock the shaft 61 On the outer end of the said rock-shaft is rigidly secured an upturned rocker-arm d to which is pivotally connected at d a pawl (1 adapted to engage and rotate, step by step, a ratchet- Wheel 0, forming a part of the measuring mechanism to be hereinafter described.

The starting and stoppingshaft b has fast I release the shoulder from the holding-plate, j the upper end of the knock-off 'lever being slightly separated from the upper end of the shipper-rod, as shown.

The upper end of the rocker-arm d has piv-' otally mounted upon it at d a latch (i (shown separately in Fig. 3,) said latch being herein formed as a bent lever with one arm normally extending over the top of the knock-off lever b and provided with a laterally-extended too (1 adapted to enter between the shipper-rod and the knock-off lever when the machine is to bestopped automatically. The other arm of the latch is upturned at al and is acted upon by a pin or stud a), extended laterally from a normally-vibrating arm a, fulcrnmed at a and vibrated in usual manner, said arm being common in warping-machines as forming apart of the stop-motion mechanism thereof. The vibrations of said arm and the rocker-arm d are so timedthat ordinarily the latch (i will be maintained in inoperative position with its too (1 above and out of engagement with the knock-off lever as the rockerarm swings back and forth; but when the vibrator a is held from coming back the latch is released, its too 61 engages the upper end of the knock-0E lever b, and as the rocker- ICQ arm d swings back said lever Z) will be rocked to release the shipper-rod 19 An extension 10 of the rocker-arm serves as a back-stop for the arm d of the latch and prevents it from being thrown too far back.

Returning now to the measuring mechan ism the ratchet-wheel c has an attached worm 0 in mesh with a worm-gear 0 fast on an upright shaft 0 supported in suitable bearings on the frame and having at its upper end a worm 0 which drives the warper-clock, as it is termed. This clock has a worm-gear c in mesh with and rotated by the worm c and a worm 0 having a deep groove, is rotated by and with the gear 0 there being a slot 0 at the end of the groove. A finger 0 mounted to slide on a rod 0 travels in the groove and is held therein in any suitable manner, as by a weighted arm 15, bearing against the finger, the finger dropping into the slot 0 when it reaches the end of the groove in the worm c. The upper end of the finger, beyond its fulcrum, has attached adjustably thereto by a set-screw 5 a stop, shown as a rod 0 with a shoulder or head 0 normally held in the position shown in Fig. 1, above a long roll or stud a extended laterally from the vibrator a, so as not to interfere with the movement of the latter. When the finger 0 reaches the end of the groove in the worm c it drops into the slot 0, turning said finger on its fulcrum and permitting the head 0 of the stop to drop down behind the roll a as the vibrator (1 moves to the right, Fig. 1, into dotted-line position and preventing the return movement thereof. The stud a is thus held away from the latch (1 so that on the forward swing of the rocker-arm d the toe c of the latch engages the upper end of the knock-off-lever Z2 turning the latter as the rocker-arm swings back, and thereby releasing the shipper-rod b to effect the shifting of the belt and stoppage of the machine.

An eccentricfis mounted on a pivot f on the frame A, engaged by a strap f, secured to or forming part of an elbow-leverf f, the depending arm f having a lateral lngf beneath the pawl d, the longer arm f being shouldered at S and extended through a hole 18in the shipper-rod. A handlef is secured to the eccentric fto rotate the latter on its pivotf and thereby move the elbow-lever in one or the other direction.

It is sometimes necessary or desirable to run the drum D before the beam is applied and before the winding of the yarn is begun, and at such time the handle f is turned to the right, Fig. 1, to move the eccentric-disk f on its pivot f and thereby through the lug f lift the pawl, but at the same time the shoulder S operates to release the shipperrod 13 from its holding-plate. It is therefore necessary for the operator to keep the treadle B depressed so long as the machine is running with the clock mechanism inoperative, so that the machine cannot run while the attendant is absent unless the ratchet-wheel 0 is turning by the action of the pawl (1 the return of the diskfto the position shown in Fig. 1 being necessary before the shipper-rod can engage its holding-plate.

By operating the measuring mechanism from the drum which drives the beam by surface contact there is practically no slip whatever, owing to the great weight of the beam.

WVhen the diskfis in the position shown in Fig. 1, it will be manifest that if the arm f 3 of the elbow-lever is lifted the arm f will be swung to the right and upward to release or lift the pawl. The free end of the armf is extended through the hole 18 in the shipper-rod b and when the latter is released from its holding-notch it rises, and thereby lifts the outer end of the arm f rocking the elbow-lever and releasing the pawl, as has been described, so that movement of the shipper-rod into operative position effects the release of the pawl.

My invention is not restricted to .the precise construction and arrangement herein shown and described, as the same may be varied without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a warping-machine, stopping means, warp-measuring mechanism to effect the operation of said means when a predetermined length of warp has been wound, actuating means for the measuring mechanism, and a device intermediate said actuating and stopping means, to maintain one operative when the other is inoperative, and vice versa.

2. In a warping-machine, a Winding-drum, measuring mechanism for the warp, means actuated by the drum to operate said mechanism, stoppingmeans for the machine, operative by or through the measuring mechanism when a predetermined length of warp has been wound, said means including ashipperrod and its holding member, and a manuallycontrolled device to render inoperative the means for actuating the measuring mechanism and to maintain the shipper-rod out of engagement with its holding member.

3. In a warping-machine,the winding-drum, measuring mechanism for the warp, a pawl and ratchet actuated by the drum, to operate the measuring mechanism, stopping means, including a shipper-rod, a releasing device for the pawl, operated by said rod, and con nections between the rod and the measuring mechanism, to release the former when a predetermined length of warp has been wound.

4. In a warping-machine,the winding-drum, warp-measuring mechanism actuated thereby, operating connections between them,stopping means, operative by or through said measuring mechanism when a predetermined length of warp has been wound, said stop ping means including a shipper-rod and its holding member, a device intermediate the shipper-rod and the connections between the inoperative latch carried thereby, to engage and operate the knock-off lever, and latch controlling means governed by the measuring mechanism and operative to release the latch when a predetermined length of warp has been measured.

In testimony whereof I have signed my .name to this specification in the presence of' two subscribing Witnesses.
